SSH Agent on OS X

There’s a lot of information on the intertoobs about getting ssh-agent “working” in OS X and even more articles about when and how the stock behavior of ssh-agent changed (mostly with respect to how ssh-agent interacted with the Keychain).

This article doesn’t cover or care about any of that.

This article is concerned with:

  • Enabling ssh-agent in such a way that I can “ssh-add” in one terminal window and that same agent (and the loaded keys) is available in all of my other terminal windows.
  • Enabling use of ssh-agent from MacPorts and/or Homebrew and not the older ssh-agent that OS X ships with in /usr/bin.
  • To avoid having to put my keys in the Keychain (just a matter of preference).

OS X – Outlook Search “No Results”

The worst feeling for a geek:

This has happened to me twice now: upgrading Mac OS X from one release to another and after the dust settles, the search function in Outlook 2011 totally breaks and always returns “no results”. As we all know, email sucks and being able to deftly search through that mound of crap in your mail client is the only thing that makes it somewhat bearable.

My Tools for Studying

fry-not-sure-if-studying As I wrote about before (Creating a CCNA Voice Lab) I’ve been studying for another Cisco certification. As I was studying for the exam, I started thinking about the tools I was using to prepare. It wasn’t that long ago that my tools were limited to pen and paper (does that make me sound old?? Uhhg). Now, I have a tablet, smart phone, and of course the venerable “cloud” for storing PDFs, notes, etc.

Anyway, I thought it would be neat to document the tools I’m using today. It’ll be interesting to read this in a couple of years to see how things have changed again and maybe it’ll give a fellow cert-chaser some ideas for today. Continue reading My Tools for Studying

mDNS Gateway in the Cisco Wireless LAN Controller

I’m not sure why I’ve taken such an interest in mDNS, service discovery, and the Bonjour protocol, but I have. It probably has something to do with my not being able to use AirPlay at home for such a long time because, like any true network geek, I put my wireless devices on a separate VLAN from my home media devices. I mean, duh. So now I keep an eye out for different methods of enabling mDNS in the network in anticipation of my own experience in my home network becoming one of my customer’s experience in their enterprise network.

AirPlay, VLANs, and an Open Source Solution

As I’ve written about in the past (here), Apple’s AirPlay technology relies on Bonjour which is Apple’s implementation of “zero config” networking. One of the things that Bonjour enables is the automatic discovery of services on the network. For example, an Apple TV might advertise itself as being able to receive AirPlay streams. An iPad that is looking for AirPlay receivers would use Bonjour to discover the Apple TV and present it to the user as an AirPlay destination. Both the Apple TV and iPad do all this without any user intervention or configuration (hence the “zero config” part).

That’s fine and dandy but what my earlier article focused on was how Bonjour broke down in a network where what I’ll call the “server” and the “client” are not in the same Layer 2 domain/VLAN. This is because the service discovery aspect of Bonjour relies on link-local scope multicast. These packets will not cross Layer 3 boundaries in the network.

Android vs iOS: Opinions From a Long-Time Android User

I don’t really keep up to speed on consumer technology. For me, the enterprise IT space holds more challenge and interest. There is one piece of consumer tech though that has become fully ingrained in my life: the tablet. For that reason, I’m going to summarize my experience in using both Android and Apple based tablets.
